I've tried everything, followed the destructions to the letter, tried for rolling codes etc. Even been on the homelink site to ensure my owners manual instructions match what homelink says.
Since first posting I can now get my old transmitters working or my wireless keypad but not both and I cannot get homelink to bite at all.
I like Maddog's idea, that will be next.
Not a huge deal if I don't get it working but I just want to tell everyone I have a $40,000.00 garage door opener :P

Thanks Brad for posting the instructions, appreciate the effort.

I had similar problems with rolling codes. I gave them a call at homelink, number in your manual, and the girl there walked me through the steps. No problem. I have an Overhead Door opener, and there were specific instructions for mine. Some of them need specifics I guess. Give them a call, very helpful.
